I use led lights in floral design and often in underwater designs so i was thrilled to find the remote feature as the lights can be placed and then turned on for a flower show without running the battery down or disturbing the design

Have not tried all the lights to assure they work but did a couple and so far so good

Batterys died on second day of use battery dies too fast though even though youve turned them off by remote the batteries go dead in under a week
